Hi I have severous viewsheds (view1, view2, view3 etc) and I want to calculate the percent of visible areas per viewshed. I have the following code but I always get zero "0" at the second for loop and i have been trying that for hours, any help?
Thanks in advance
import arcpy
import os
from arcpy import env
from arcpy.sa import *
#workspace = arcpy.GetParameterAsText(0)
arcpy.env.workspace = "C:Visibility/Calc_View/View"
ras = arcpy.ListRasters("view*", "GRID")
#cellsize = arcpy.GetParameterAsText(1)
fields = ["VALUE", "COUNT"]
for r in ras:
with arcpy.da.UpdateCursor(r, fields) as cursor:
total = 0
for row in cursor:
total = total + row[1]
print r, total
C = arcpy.da.UpdateCursor(r, fields, """"VALUE" = 1""")
for row in C:
percent = row[1] / total
print r, percent
